• turning on Greasemonkey live editing

  - by Delirium tremens

  On Firefox, I click Tools, Addons, Extensions, Greasemonkey, Options, select my user script, click Edit, change the source code, reload one of the included pages, but the script is the unchanged version. On User Scripts, logged in, I click my username, Script Management, my script's name, Admin, Edit Code Online, change the source code, click save, the link to the install page, install and the script is the changed version. How did you turn on Live Editing? While following Greasemonkey tutorials, this feature is not working... Are you going to use the "works on my computer" excuse? Should this be on the Stack Overflow sister site Super User?

• simple photo viewer

  - by Blaise

  Hi, I am fairly new to all this. I am trying to make a simple photo viewer with javascript or anything easy to alter. I just want a next and prev. button to take you between photos. Click next and next photo shows. Just that simple. I have a flash version but I would like to avoid using flash. I've been doing it the long way by making multiple pages, one for each photo and a button that repeats. I know there must be a better way but I just can't seem to figure it out. Please help

• IIS 7.0 - Every site suddenly redirecting root request to forms authentication

  - by Pittsburgh DBA

  Suddenly, IIS 7.0 is redirecting every request for the root of any domain hosted on the box to ~/Account/Logon, which is our Forms Authentication redirect. Additionally, some JavaScript and image requests are being similarly redirected, but not other aspx pages. This is not desirable. Nobody will admit to changing anything. Any ideas? EDIT: It turns out that something has gone wrong with the disk permissions. Can anyone point me to the way things are supposed to be in Windows Server 2008 for a standard ASP.Net installation? The disk permissions are out of whack now.

• Redirect away from HTTPS with ASP.NET MVC App

  - by Amadiere

  I'm using ASP.NET MVC 2 and have a login page that is secured via HTTPS. To ensure that the user always accesses those pages via SSL, I've added the attribute [RequiresHttps] to the controller. This does the job perfectly. When they have successfully logged in, I'd like to redirect them back to HTTP version. However, there isn't a [RequiresHttp] attribute and I'm struggling to get my head around how I might achieve this. The added (potential) complication is that the website when in production is hosted at the route of the domain, but for development and testing purposes it is within a sub directory / virtual directory / application. Am I over-thinking this and is there an easy solution staring me in the face? Or is it a little more complex?

• Seam page navigation with includes

  - by Marc

  Hello, I'm using seam page navigation rules. and did not experience any problem with adding rules which redirect from one page to another. But since I designed my page views using those redirection simply don't happen anymore for those pages. Tried to define the rule to the view that gets included, then to the view that includes the others (which to me was making more sense) but none work. Is there anything special about page navigation in seam using included view-id ? I'm using jsf, xhtml as my page views. Thanks

• How do I protect myself?

  - by ved

  I was poking around at my work computer this evening and was looking at my timesheets. I noticed that all my timesheets had variables in the URLs and I could figure out the numbering scheme for the pages. Then I got a little curious about SQL injection and thought of trying out adding simple SQL injections like "OR 1=1" etc. to see how protected we really were with our timesheet info. One of these strings yielded a friendly error page saying that an error email was sent to the developer. I am concerned that my ID, and request will be seen by the developer , immediately recognized as SQL injection and will be reported to network security officer as a malicious attempt by an employee to hack the timesheet dB. what is my defense? I am really worried.

• Programmaticaly grabbing text from a web page that is dynamically generated.

  - by bstullkid

  There is a website I am trying to pull information from in perl, however the section of the page I need is being generated using javascript so all you see in the source is <div id="results"></div> I need to somehow pull out the contents of that div and save it to a file using perl/proxies/whatever. e.g. the information I want to save would be document.getElementById('results').innerHTML; I am not sure if this is possible or if anyone had any ideas or a way to do this. I was using a lynx source dump for other pages but since I cant straight forward screen scrape this page I came here to ask about it! If anyone is interested, the page is http://downloadcenter.trendmicro.com/index.php?clk=left_nav&clkval=pattern_file&regs=NABU and the info I am trying to get is the row about the ConsumerOPR

• Why does it make a difference where I include the jQuery script file?

  - by Matthew Jones

  On my master page (for all pages in my site) I have a ToolkitScriptManager. On my content page, there are a series of hyperlinks and divs for collapsible functionality. The code to show/hide the panels work like the following: $('#nameHyperLink').click(function() { var div = $('#nameDiv'); var link = $('#nameHyperLink'); if (div.css('display') == 'none') { link.text('Hide Data'); div.show('100'); } else { link.text('Show Data'); div.hide('100'); } }); If I include a ScriptReference to the jQuery 1.4.2 file in the toolkitscriptmanager, the javascript code is executed incorrectly on the page (only the text for the hyperlink is changed, the div is not actually shown.) However, if I don't include the jQuery file in the ToolkitScriptManager and instead include it in the content page, it works correctly. I'm a Javascript/jQuery newbie, and this makes no sense at all. What's going on here?

• Why do mainframe greybeards refer to DB2/zOS as "he"? [closed]

  - by Alex Nauda

  If you ask a DB2/zOS engine DBA a question about DB2's behavior, the DBA will refer to the DB2 engine as "he" much the way a sailor uses "she" to refer to his ship. For example: "Once you fill the freespace, DB2 still wants to keep those rows in cluster order in the tablespace. That's why he'll split that page in half, and you end up with lots of half-empty pages. That is, unless the cluster key of the row you've just inserted is the highest in the table, in which case he makes a new empty page, and he puts just your new row into that page. So I wouldn't have to do this REORG if you would just sort your input like I suggested." Does anyone know where this tradition comes from?

• Script Errors in Silverlight WebBrowser Control

  - by Whiskas

  Hi, I am showing a HTML page with a Flash video player on it in a Silverlight app using the WebBrowser control. The site itself is displayed perfectly and everything works just fine. But when I want to close the player component, I somehow need to completely dispose the current HTML page with the flash player. I tried navigating to about:blank, or even to other pages like google.com before the player component is hidden. But the flash video keeps on playing and the WebBrowser shows several Script Errors, which must be clicked in order to really leave the flash page. Is there any way to instantly "clear" the WebBrowser control or to surpress the Script Errors so that it leaves the html/flash page? In WPF there seem to be some methods for that, but I couldnt find any on the Silverlight WebBrowser control. Any hints are appreciated, Whiskas

• Displaying untrusted HTML using PHP

  - by esryl

  I have a read a number of excellent questions and answers today about dealing with user input. I am now using htmlspecialchars() to display user data in the create/edit forms (but accepting the raw input via prepared PDO statements into my database). The main question I know have is, what do you do when you are allowing the user to submit HTML which will then be displayed to the public. Obviously htmlspecialchars() is no longer suitable as it just encodes the tags and renders the content useless for purpose. My application is currently accepting HTML from an admin for product descriptions. This would allow a malicious admin to inject potentially unsafe data into public facing pages. How do people cope with this?

• Master report and subreport communication

  - by Dave Jarvis

  How do you determine whether the content for the detail page being displayed is filled by a specific subreport? For example, consider two subreports on the same master report, using different detail bands: Detail 1 Detail 2 The header on the master report should show certain fields on pages where the subreport in the Detail 2 band is printed. A Return Value from the subreport in the Detail 2 band only seems to be set after the report has finished, even though the Reset type for the variable (in both the master and the subreport) is set to Page. (Setting it to Report also does not help.)

• Python os.path.join

  - by Jim

  Hello, I am trying to learn python and am making a program that will output a script. I want to use os.path.join but am pretty confused (I know I am very bad at scripting/programming) See, according to the docs ( http://docs.python.org/library/os.path.html ) if I say os.path.join('c:', 'sourcedir') I get C:sourcedir as it's output. According to the docs, this is normal (right?) But when I use the copytree command, Python will output it the desired way, for example import shutil src = os.path.join('c:', 'src') dst = os.path.join('c':', 'dst') shutil.copytree(src, dst) Here is the error code I get WindowsError: [Error 3] The system cannot find the path specified: 'C:src/.' If I wrap the os.path.join with os.path.normpath I get the same error If this os.path.join can't be used this way, then I am confused as to its purpose According to the pages suggested by Stack Overflow, slashes should not be used in join--that is correct I assume? Thanks guys(girls) for your help

• ASP.NET OutPutCache VaryByParam and VaryByHeader with AJAX

  - by DennyDotNet

  I'm trying to do some caching using VaryByParam AND VaryByHeader. When an AJAX request comes in I return a partial XHTML. When a regular request comes in I send the partial XHTML page with header / footer. I tried to cache the page by doing: [OutputCache( Duration = 5, VaryByParam = "nickname,page", VaryByHeader = "X-Requested-With" )] However this doesn't work... if I do a regular request first then run the AJAX call I get the full cached page instead of the partial and vice-versa. Seems like VaryByHeader is being ignored. Is it because X-Requested-With is omitted on normal requests? Or perhaps it's doing VaryByParam OR VaryByHeader? My obvious way around this is for AJAX requests to call a different method which only returns partial pages, however I'd like to avoid that if possible. I'm using ASP.NET MVC 1.0 with the OutputCacheAttribute.

• Extra blank page when converting HTML to PDF using abcPDF

  - by ProfK

  I have an HTML report, with each print page contained by a <div class="page">. The page class is defined as width: 180mm; height: 250mm; page-break-after: always; background-position: centre top; background-image: url(Images/MainBanner.png); background-repeat: no-repeat; padding-top: 30mm; After making a few changes to my report content, when I call abcPDF to convert the report to PDF, suddenly I'm getting a blank page inserted after every real report page. I don't want to roll back the changes I've just made to remove this problem, so I'm hoping someone may know why the extra pages are being inserted.

• Specification: Use cases for CRUD

  - by Mario Ortegón

  I am writing a Product requirements specification. In this document I must describe the ways that the user can interact with the system in a very high level. Several of these operations are "Create-Read-Update-Delete" on some objects. The question is, when writing use cases for these operations, what is the right way to do so? Can I write only one Use Case called "Manage Object x" and then have these operations as included Use Cases? Or do I have to create one use case per operation, per object? The problem I see with the last approach is that I would be writing quite a few pages that I feel do not really contribute to the understanding of the problem. What is the best practice?

• Monitoring outgoing internet traffic

  - by Frane

  Is there a way to monitoring internet traffic programatically? I would like to log the pages users are visiting on the Internet. Can this be achieved with .NET code, is there a 3rd party .NET component that could be used to retrieved data. Information about Internet traffic must be stored to a database so I cannot use a plugin or something for IE. We are also looking to include this code into our existing product so we cannot use a 3rd party product that cannot be redistributed. It would be cool if this thing could monitor traffic for all browsers but monitoring IE traffic might also be sufficient.

• Trouble using genericra to integrate activemq and glassfish when using failover protocol

  - by Kyle

  Hi, I'm attempting to use activemq in glassfish using the genericra resource adapter provided with glassfish 2.1. I have found a few pages with helpful information including http://activemq.apache.org/sjsas-with-genericjmsra.html. I have actually had success and been able to get MDBs to use activemq as their JMS provider, but I'm running into an issue as I'm trying to do some more complicated configuration. I want to set up a master-slave configuration, which would require my clients to use a brokerURL of failover:(tcp://broker1:61616,tcp://broker2:61616). In order to do this, I set the following property when calling asadmin create-resource-adapter-config (I have to escape '=' and ':'): ConnectionFactoryProperties=brokerURL\=failover\:(tcp\://127.0.0.1\:61616,tcp://127.0.0.1\:61617) However, I am now getting a StringIndexOutOfBoundsException when my application starts up. I suspect the comma in between the two URLs is the culprit, since this works fine: brokerURL\=failover\:(tcp\://127.0.0.1\:61616) Just wondering if anyone has dealt with this issue before. Also wondering if there is a better way to integrate with glassfish than using the generic resource adapter.

• What is a good Java web crawler library?

  - by DrDee

  Hi, I am about to develop a crawler in Java but don't feel like reinventing the wheel. A quick Google search gives a whole bunch of Java libraries to build a web crawler. Besides that Nutch is of course a very robust package but seems a bit too advanced for my needs. I only need to crawl a handful websites a week containing a couple of 1000 pages each. Which open source Java library would you recommend considering: speed multithreading (or even distributed) extending it with new functionality active maintained and documentation?

• How to make script paths inside user control independent of page hierarchy.

  - by Rohit

  My website is organized in the following folder structure Root Pages CustomerManagement DepartMentManagement Script UserControls Now i have a user control inside userControl Folder. I have to use a external js file. So i use it this way <script type="text/javascript" language="javascript" src="../Script/slider.js"></script> My understanding is that since both are under root so i have used a single .. Now what happens is that when this usercontrol is used inside DepartMentManagement it checks for script folder inside CustomerManagement as .. refers to one hierarchy above and script file is not found.Even using a ~ doesnot work. I want to make this script path independent of the path where this control is used. I don't want to move script reference code to the page as control requires script mot page.Please tell me how to achieve this.

• Why would an ASP.NET site become veeeeeery slow after the network connection dropped?

  - by Joon

  I have an ASP.NET 3.5 site published in IIS 7.5 on Windows Server 2008 R2 64 bit. The pages are accessed over SSL One of our testers has determined that if, during a postback, he blocks network access on his PC, and then after a few seconds reconnects, our site becomes excruciatingly slow. Like 30 seconds per page load. If he hits the refresh button in his browser it stays slow. If he closes the tab, then re-opens it, it becomes fast again. This behavior happens with both IE 8 and the latest firefox. There are no event log entries on the server when this happens My question: - Has anyone seen this same behavior? - Does anyone have a theory as to what causes it?

• Clustered index dilemma - ID or sort?

  - by richardtallent

  I have a table with two very important fields: id INT identity(1,1) PRIMARY KEY identifiersortcode VARCHAR(900) My app always sorts and pages search results in the UI based on identifiersortcode, but all table joins (and they are legion) are on the id field. (Aside: yes, the sort code really is that long. There's a strong BL reason.) Also, due to O/RM use, most SELECT statements are going to pull almost every column. Currently, the clustered index is on id, but I'm wondering if the TOP / ORDER BY portion of most queries would make identifiersortcode a more attractive option as the clustered key, even considering all of the table joins going on. Inserts on the table and changes to the identifiersortcode are limited enough that changing my clustered index would be a problem for insert/update operations. Trying to make the sort code's non-clustered index a covering index (using INCLUDE) is not a good option. There are a number of large columns, and some of them have a lot of update activity.
